' Application filed April 26, 1920. Serial No. 376,600.

Be it known that LCHARLEs N'. CLARK,

'a citizen of the United States, residing in Somerville, county ofMiddlesex, and State of Massachusetts, have invented an Improvement inWVagons, of which the following description, in connection with theaccompanying drawings, is a specification, like characters on thedrawings representing like parts.

This invention relates to-wagons of the character employed for jdelivering coal,

gravel and like material and more part1cu larly to wagons having a tailboard or end 7 capable of being moved from both of its described.

The invention further has for its ob ect stood.

open positions into its closed position by 'mechanical means, as will bedescribed.

The invention also has for its object to provide a simple, inexpensiveand efiic ent construction of tail board. of the character toprovidethetail board with a novel con-' struction of guiding members forcoal, as will be described. These and other features of the inventionwill be pointed out in the claims at the'end of this specification.

Referring to the drawing, 10 represents the wagon body which may be ofany suitable or usualconstruction, and '12 the tail upper pivot fortheboard or end gate therefor. The tail board 12 as 'herein'shown ispivoted at ,its upper and lower ends, the pivot for'the upper end beingshownas a rotatable shaft or rod18 extended through a suitable hole inthe tail board and. provided at'its opposite ends so i with cranks 14:,15,-w'hich in the normal or r closed position of the tail board hookover "pins or lug 16, 17, carried by the sides of the wagon body- 10.-The crank or arm 15 cooperates with a spring member 18 attached towagon body 10 so as to frictionallyhold the cranks 14, 15 inlocking'engagement withthe pins 16, 17 against accidental disengagement,while permitting them to be readily disengaged by the operator turningthe shaft 13 in the proper direction through a" handle 19 on the crank15, when it is desired to lower the tail board :12 into a horizontal orshoveling position'shown in Fig.3.

The tail board 12 is provided at its lower end with a pivot shaft or rod20, which is normally supported in bearings, shown as hooksor bentrodsor arms 21 projecting radially from a shaft 22 rotatablymounted inbearings, shown as staples or eyes 23 attached to the wagon body 10.

The rotatable shaft 22 is providedat one end with a substantially longcrank or arm 24, by means of which the operator can turn the shaft 22 soas toloiverthe hooks or bearings 21 from the pivot rod 20, see Fig.

1, andthus disconnect the lower end ofthe tail boardfrom the wagon.body, to allow the operator to turn thetail board on its upper pivot 13and move its lower end away from the wagon body into 'its dumpingposition'shown in Fig. 4, in which position an opening is afiorded forthe passage of-the coal'out of the wagon body especially. when the frontend thereof islifted.

Provision is made for closing the open ing referred to'at theoppositesidespf the tail'board fora substantial distance above thelatter, so'asto avoidlateraldis'placersubstantially a quadrant of acircle and is provided with a substantially horizontal bot tom edge 26,a substantially vertical outer edge 27-and acurved edge 28. --Theclosure member is loosely mounted 'on the lower pivot 20 for the'tailboard, and is connected with the tail board by a'pin'and-slot-comnection, bent pin 30 afiixed to the tail board beingextended through acurved slot 31 in the closure member 25, the pivot 21) constituting thecenter for the curved slot 31. This pin and slot connection allows thetail board to be moved outward ifroin its closed or vertical positionshown in Fig 1, into its open or inclined position shown in Fig. 4 withthe side closure members movable in a substantially straight directionwith the front or free end of said closure,

member sliding across andbeing support-ed by the shaft- 22.

Provision is made for moving the tail board into itsclosed'position fromits open shoveling position'and from its open dump- ,ingiposition, witha minimum effort on the part o ftheoperator. To this end, they clo isure members25 on opposite sides of the tail board are connected to aWindlass or rotatable'shaft &0 extended transversely under the wagonbody and suitably supported therefrom. The shaft a0 is preferablyconnected with the closure members by chains 41, which are showna-sengaged with hooks 42attached to said closure members. The shaft 40 isprovided with a handle 43 for turningit and with a ratchet wheel4A;fwith which cooperates a holding pawl 4:5pivoted tothe wagon body.

.4 Provisionis also made for sustaining the tail board and the weight ofthe coal thereon of the hooked member 46 and is engaged thereby when thetail boardiis in its shovel m position, see Fig 3, and from which said 2hookedm'eniber is automatically disengaged when the Windlass is turnedto wind the chains 41 thereon.

v Provision'is also made for retainingthe bearing members'QI forthelpivot 20 of the A tail board in operative relation with the latteragains't accidental disengagement To this end, the wagon body 10 hassecured to it a springmeinber 5O betiveen the outer end of which andthe'wagon body the tree 7 end of the cranlr or arm 24 is normally it isdesired to move the crankor arm 24 placed, The crank or arm 24 possessessufiicient spring'to enable it tobe moved downward suiiiciently toremove it from engagement with the spring'member 50, when up into'thepositionshownin'Fig; 1 and therebyvrelease the pivot 20 ot thetailboard;-

, The tail board may andp'referablywill be p-rovided with-the usualopenin'g'52, see

Fig.- 5, through which the coalma'y beldisa charged with the tai'lzboardin its closed a basketor other receptacle placed in line with saidopening, whereby loss of coal and the labor and time of cleaning up thesidewalk or driveway after the coal has been delivered may be reduced toa minimum. To this end, the, tail board is provided with wings, ormovable guiding members 5a, which are irnounted to turn on stationaryvertical pivot rods 55, and which are provided with curved uppersurfaces 561 suit; ably shaped to ha-vea cam action and which cooperatewith the lower edge of the sliding cover 535 so that when the saidcover' is moved downward to close the opening 52,

the lower edge of said cover will slideover' the upper curved surface 56andwillturn the coal guiding members 54011 their pivots from their openposition]represented in Fig. 7 into their closed position, 'in';whichthey extend across the opening 52 substantially in the plane of the tailboard. Thefsliding cover 58 is movablebetween vertical guides 58 and maybe moved by a'lever 59 in a manner well understood.

From the above description it will be, seen that while the load is intransit, the tail board is in its closed position shown in Fig. I and isheld vin this position by the holding pawl 45 otthe Windlass.

.VVhen it is desiredto shovel the load from the wagon, the'tail board ismoved into its horizontal position. shown in Fig; 3, which is effectedby the operator throwing back the holding pawl .5, and rotating theupper pivot or shaft-l3 to release the upper end of the tail board,which leaves the latter tree to be turned downby gravity assisted it maybe b ytheoperatorl until. theho'oked members 46 engage the stops orsustaining members 4:7,;18' shown in Fig; 3. It it is. desired to dumpthe 00211, the handle or crank 24: is disengaged fromits. holding member50 and turned up into the position shown in Fig; 4. soasTto release ,thetail board at its lower end, which is then pushed outbv' the load intothe position shown in Fig. 4:. i

()ne embodiment of the'invention is herein shown, but it is not desiredto limitthe invention t6 the particular constriiction shown.

From the above descriptiom it will be seen that a single operator fromone side of the wagon can control the tail board so that it can beplaced into a shovelling position or:

into a dumping position as he desiresand can close the tail board fromeither position and lock it in its closedpositiOn. i

The pin and slot connection 30', 31, ispreferably arranged so that thepin30 is imade shorter than the length ofslot 31 and is capable of beingturned into alignment with the slot so as to permit the side closuremem- V bers 25 to be sprung laterally and disengaged from the pins 30,and thereby leave the tail.

board, when released at its upper end, to be turned down into asubstantially vertical position on the pivot 20, when it is desired toload the wagon body by shoveling from 2. The combination with a wagonbody, of

a tail board pivotally secured thereto at its upper and lower ends,means for detachably securing said pivoted upper and lower ends to saidwagon body, side closure members pivotally secured to the lower end ofsaid tail board, and a Windlass carried by the wagon body and connectedwith said side closure members to move thetail board from both of itsopen positions into its closed position.

3. The combination with a wagon body, of a tail board pivotally securedthereto at its upper and lower ends, means for detachably securing saidpivoted upper and lower ends to said wagon body, side closure memberspivotally secured to the lower end of said tail board, and mechanicalmeans carried by said wagon body and operatively connected with saidside closure members to move the tail board from both of its openpositions into its closed position.

4;. The combination with a wagonbody, of a tail board cooperatingtherewith, upper and lower pivots forsaid tail board carried bysaid tailboard, means on the wagon body co-operating with the upper pivot tosecure the latter to the wagon body, side closure members co-operatingwith said tail board and wagon body and inwhich the lower pivot for thetail board is mounted, means for. con-- necting the side closure memberwith the tail board to permit the latter to turn on the lower pivot andbe moved with respect to said side closure members, and means carried bysaid wagon body for detachably supporting the lower pivot for the tailboard. 7

5. The combination with a wagon body, of atail board or end gatetherefor provided with an opening for the discharge of the contents ofthe wagon body, pivoted side guides for said contents cooperating withsaid opening, and a slide to cover said opening cooperating withsaidside guides to automatically turn the same from: their op'er-,

ative into their inoperative position, when said slide is moved to closesaid openlng.
